I had the exact same problem and i managed to fix it by randomly changing my PCI-Express BIOS settings I spent weeks trying to figure out why it was freezing loading ubuntu, even from the livecd, then i tried unpluging my pci-express card and pluging in the integrated graphics and it worked! so i thought it was my graphics card (ati) so i changed it for my mums just to test it but still locked up. so i thought.. must be a pci-express problem.
heres how i fixed it. 1. restart and go into the BIOS settings (usually F2 or del) 2. go to the advanced options > Chipset Configuration > PCI Express Configuration 3. then disable the option 'Compliance Test Pattern 4. you may still get the 4294671.433000] PCI: Cannot allocate resource of region 3 of device 0000:00:00.0 [4294671.433000] PCI: Cannot allocate resource of region 3 of device 0000:01:00.0 [4294671.433000] PCI: Cannot allocate resource of region 0 of device 0000:02:00.0 errors flicker on the screen but at least mine booted and worked sweet after i did that hope it helped -- freeze at startup https://bugs.launchpad.net/bugs/38263 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
